MACHlNE FOR MAKING WIRE COILS FOR FLEXIBLE SHAFTING.

SPECIFICATION forming part of Letters Patent No. 593,168, dated November 2, 1897.

Application filed March 1, 1897. 3 Serial No. 625,648. (No model.)

To all whom it may concern.-

Be it known that I, ADOLPH STRIEMER, merchant, a subject of the King of Prussia, German Emperor, and a resident of 5 Goutard strasse, Berlin, Empire of Germany, have invented certain new and useful Improvements in Apparatus for Manufacturing Wire Coils for Use in Flexible Shafting, of which the following is a specification.

This invention relates to improvements in apparatus for mani'ifacturing wire coils having two or more separate wires for use in connection with flexible shafting.

In manufacturing these wire coils or spirals the wires for use therein are, according to this invention, passed separately through or over a hollow shaft, which is provided with suitable guides or grooves to receive them. The hollow shaft is fitted at the rear with aspoolcarrier arranged to hold the required number of spools. The opposite end or front of this shaft is provided with a head for causing the wires to be wound upon a mandrel arranged in the interior of the hollow shaft and adapted to advance gradually with the finished part of the coiled wires. The spools and the head are so constructed asto prevent as much as possibleall friction and bending or kinking of the wires in the guides or grooves. The wires pass from such grooves over two rollers on the head and into a device for guiding them onto a mandrel.

In order that my invention may be readily understood, I will describe the same fully with reference to the accompanying drawings, in which- Figure 1 is a side elevation, and Fig. 2 a front elevation, of the improved apparatus. Fig. 3 is a longitudinalsection of part of the hollow shaft and connected parts, drawn to a larger scale. Fig. 3 is a' cross-sectionof the same. Fig. aillustrates the mode of guiding the wires of the head of the apparatus. Fig. 5 is a rear view of the apparatus, showing the spool-carrier, which in this instance is adapted to carry four spools. Figs. 6 and 7. show the construction of the spools. Figs. Sand-9 show the wire-guiding device which is fitted to the head of the apparatus.

The hollow shaft consists of two tubes is and Z, arranged one within the other. To-the outer tube are fitted a spool-carrier n, ahead e, and bearings 10. It is also provided with lateral slot-s m m, which lead to the interior. The inner tube Z is provided with a windingmandrel s and with guides or grooves i for the wires.

The spools containing the wires for use in manufacturing the coils are mounted on pins 0 in the carrier 72. These spools consist of two disks q, mounted on a boss (IX and having arranged between them a spring band or ring g. This ring is made in the form shown in Fig. 7 and has its ends overlapping, one end being provided with a guide-pin qfladapted to work in a slot (1 in the other end.

At the front end of the hollow shaft is the head a, which is provided with arms 6, on which are mounted rollers a, b c d and a b c d and with a wire-guiding device f, protected by a cover g.

It may be mentioned that the guide shown at Fig. 8 is for left-hand spirals or threads, While that shown at Fig. 9 is for right-hand spirals or threads. These guides are furnished with a central hole h and with facegrooves '11, running from the outer edge toward the periphery of the hole h, through which latter the mandrel .5 passes.

According to whether a left-hand or a righ thand spiral or thread-guide f is being used the arms e, with their rollers (Lb c d and a b c (1, require to be placed in one or the other position, either as shown in Fig. 2 or with the rollers a a reversed, so as to bring them into the position of the rollers b b, and vice versa.

In order tosupply the spools q with the wire for manufacturing the spirals, I proceed as follows: A spool q is taken from the carrier n, and after one of its disks has been removed a coil of the wire to be used is placed over the springband q, and after replacing the solid disk q the spool is returned to the pin 0 in the carrier. Having filled all the spools in a similar manner, the outer end of each coil of wire is unfastened and passed through one of the slots on in the hollow shaft and into one of the guides or grooves 'i, then led out through one of the slots m and over the rollers-say a aand into one of the guides or grooves '5. After having inserted the required number of wires from the spools-in this manner the ends of the wires are fastened to the winding-mandrel s. This mandrel is adapted to move endwise by any suitable means, (not shown,) but does not revolve with the hollow shaft. The bearings 10 en able the apparatus to be revolved, so as to cause the wires m, and so on) tobe wound upon the mandrel s and form a spiral having two or more separate wires. The finished part of the spiral, together with themandrel 5, passes gradually out of the rear of the apparatus.

According to a modification the spool-cam rier n and the head 6 may be mounted directly on the tube Z, and the tube in such a case would be made stronger and would be provided with a number of guides or grooves equal to the numberof wires to be used. One of the bearings w would be arranged on the tube l near the front end of said grooves, so as to cover the grooves at that part. In order to retain the separate wires each one within its groove on the tube Z, a removable case or several loose rings may be placed on such tube at suitable distances apart.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is

I 1. A coiling apparatus consisting of a hollow mandrel adapted to be rotated and provided at one end with a spool-carrying frame,

said spools consisting of pairs of disks in ounted upon pins, said disks being further provided with suitable means for fixing them together,said mandrel terminating at the other extremity in a frame carrying rollers adapted to facilitate the feeding of the wires; said mandrel being furthermore provided with two series of slots arranged opposite to the spools and adapted to afford to the wire an entrance into and an exit from the hollow mandrel aforesaid; and suitable mechanism arranged within the said mandrel and adapted to extend beyond the roller end of the apparatus, substantially as described.

2. The herein-described spool consisting of a central boss, two disks, one of whichis secured on each end of the boss, and a spring band or ring loosely placed around the boss and between the disks, one end of said ring having a groove, and the other end having a pin to engage in said groove when the ends are overlapped, rendering the ring self-adj ustin g as to size, all substantially as set forth.

3. The combination with the head 6 of the hollow shaft, of the bracket-arms e mounted thereon and projecting diagonally therefrom,

the rolls a, a, b, b, c, c, and d, d, reversibly I mounted on said arms, and the guide f for receiving the rollers, having guideways leading to the central opening, all substantially as set forth.

4. A coiling apparatus consisting of a suit series of rollers arranged in pairs and adapted to convey the wires from the exit-grooves to the fixed mechanism aforesaid, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 15th day of'February, 1897.
